BACKGROUND The purpose of this study was to assess the relationship of CT-perfusion (CTP), 18F-FDG-PET/CT and histological parameters, and the possible added value of CTP to FDG-PET/CT in the initial staging of lung cancer. METHODS Fifty-four consecutive patients (median age 65 years, 15 females, 39 males) with suspected lung cancer were evaluated prospectively by CT-perfusion scan and 18F-FD...
In all previous kinetics studies of calf liver CTP synthetase, simple Michaelis-Menten hyperbolic plots were obtained. In this study it was shown that calf liver CTP synthetase could generate sigmoidal kinetic plots as a function of the substrate UTP when in the presence of the product of the reaction, CTP. The Hill number was estimated to be 2.8. The enzyme did not generate sigmoidal plots as ...
Differences in research methodology have hampered the optimization of Computer Tomography Perfusion (CTP) for identification of the ischemic core. We aim to optimize CTP core identification using a novel benchmarking tool. The benchmarking tool consists of an imaging library and a statistical analysis algorithm to evaluate the performance of CTP. The tool was used to optimize and evaluate an in...
BACKGROUND AND PURPOSE Reliability of CT perfusion (CTP) algorithms has not been fully validated. We investigated whether the cerebral blood flow (CBF) values obtained by using a dynamic CTP technique with a tracer delay-insensitive deconvolution algorithm are more accurate than those obtained by using CTP with delay-sensitive algorithms in unilateral cerebrovascular steno-occlusive disease, wh...
OBJECTIVES To assess the feasibility of studying the comparative effectiveness of the Childhood Arthritis and Rheumatology Research Alliance (CARRA) consensus treatment plans (CTPs) for systemic Juvenile Idiopathic Arthritis (JIA) using an observational registry. METHODS Untreated systemic JIA patients enrolled in the CARRA Registry were begun on one of 4 CTPs chosen by the treating physician...
چکیده زمینه و هدف: خونریزی ناشی از واریس مری با میزان مرگ و میر و هزینه ی بالای بیمارستانی همراه است. با تشخیص عوامل پیش بینی کننده ی خونریزی مجدد در هنگام بستری، می توان با اقدامات درمانی مناسب، از میزان بیماری زایی و مرگ ناشی از آن کاست. هدف مطالعه ی حاضر تعیین عوامل پیش بینی کننده ی خطر خونریزی مجدد در بیماران بستری شده به علت خونریزی از واریس مری با استفاده از عوامل دخیل در سیستم نمره دهی (...
BACKGROUND AND PURPOSE In recent years CTP has been used as a complementary diagnostic tool in the evaluation of delayed cerebral ischemia and vasospasm. Our aim was to determine the test characteristics of CTP for detecting delayed cerebral ischemia and vasospasm in SAH, and then to apply Bayesian analysis to identify subgroups for its appropriate use. MATERIALS AND METHODS Our retrospective...
The Carbon trading price (CTP) can best reflect the fluctuations of carbon market. This paper comprehensively analyzes CTP mechanism China’s market, discusses main factors affecting CTP, which include macroeconomic factors, energy policy and environmental provides three hypotheses. In order to highlight test hypotheses about five representative pilot markets were included: Beijing, Shenzhen, Sh...
Presence of cardiac dysfunction has been associated with an unfavorable prognosis in patients with liver cirrhosis. In the present study, 92 consecutive, newly-diagnosed patients with liver cirrhosis were prospectively evaluated. Liver disease was graded according to the modified Child-Turcotte-Pugh (CTP) score whereas left ventricular diastolic function was assessed by Doppler-echocardiography...
Abstract Cloud radiative kernels (CRK) built with transfer models have been widely used to analyze the cloud effect on top of atmosphere (TOA) fluxes, and it is expected that CRKs would also be useful in analyses surface which determines regional temperature change variability. In this study, at TOA were using Rapid Radiative Transfer Model (RRTM). Longwave (CRE) primarily driven by base proper...
